Jos,
If you want to make OMB more user-friendly, you may want to consider assigning each function to a key combination (Ctl+A/B/C/..., Alt+A/B/C/..., etc)
This way I could connect several USB keyboards, and have each of them with a Ctl or Alt key taped down, so that it would only take a single key press to activate functions or make a style selection.
Regards,
Alex
